The start: 0 to 100 km/h

Off the line, the Atto 3 Extended Range hits 100 km/h in 7.41 s versus 8.36 s for the 5 Long Range FWD. At this point, the Atto 3 Extended Range leads by 0.95 s and sits roughly 17 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Atto 3 Extended Range is doing 121 km/h against 121 km/h for the 5 Long Range FWD. The gap is 0.70 s. The challenger starts to claw back ground.

At 400 metres standing start, the Atto 3 Extended Range crosses the line in 15.57 s versus 16.27 s. The 0.70 s gap represents roughly 29 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the situation changes. The Atto 3 Extended Range maxes out at 160 km/h while the 5 Long Range FWD keeps accelerating towards 185 km/h. At 600 metres, the gap has dropped to 0.67 s.

Around 958 metres, both vehicles are level. This is the inversion point: the 5 Long Range FWD overcomes its launch deficit thanks to a 25 km/h higher top speed.

At 1,000 metres, the 5 Long Range FWD finishes in 29.07 s versus 29.19 s. The 0.13 s delta shows an extremely tight race.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Atto 3 Extended Range is capped at 160 km/h, the 5 Long Range FWD at 185 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.

With two electric powertrains, the difference comes down to power-to-weight ratio (8.58 kg/hp vs 8.33 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.50 seconds. The 0.95 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
